To all whom it may conccrrtfl'f I i appropriate to thetype of the in which my Be it known-that I FRAtIi Q ZXSSEIBEhLilQQfi invention is used a citizen of the United Statea'residing a t Akron, in the county of Summit and State of Ohio, have invented new and useful Ina provei'nents in Vehicle-'lires, of which the 1 following is a specification. I

This invention relatesv to elastic vehicletread portion of the tire. is'provided' at intergrooves, designatedin reference numerals these grooves in the same into a series of outwardly-tapering pyramidically-truncated members 5, 5. v The existence of these transverse notches 3, 3, in the main bodyportion of'theltire enables the portions which ekist between the notches to be compressed more easilyand to yield-to a" sense is to obtain from a solid tire near as possible the resiliency. and elasticity obtainable from a tire of the pneumatic type, with out the dangers of puncture incident to theuse of the latter kind.

The invention further and more specific ally aims to construct a solid tire which has an increased res'liency and requires less material to construct than the ordinarysolid terr'upted by these notches -,-From the fact With the foregoing and other objects in view, the invention consists in the novel con struction constituting the invention to be.

a definite amount -of com cushioning qualities an greatly increased, this that the' rubber whiehis isplaced by'the compression of the tread portion is permitted to expandin a longitudinal or circumferential direction, as well as transversely; whereas, inthe ordinary type of tire with an uninterrupted tread, comparatively the only possible direction in which the expansion can take place is laterally. notches in the tread portion of the tire also serves to assist in obtaining a more per-v fect traction or adhesionto the surface'on which the tire is being used, thus to a large extent eliminating the danger of skidding,

ression the tires resiliency are accompanying drawings which form a part of this specification in which is shown the referred embodiment of the invention, but it is to be understood that" changes, varia tions and modifications can be" resorted to which come within the scope-of the claims hereunto appended.

Grant, tire, my invention is equally applicable to other forms of solid tires. These tires are preferably constructed of vulcanized rubber, and the tire illustrated users of this type of device.

to construct the same and to increase the resiliency and cushioning ualities thereof, I locate'at intervals throug out the tire body a plurality of preferably unobstructed open .ings 4, arranged transversely of the bodynf the tire and preferably placed on the medial line between the notches 3, 3, thereby de creasing theamount of rubber-contained in the members In forming these'openings 4,

upwardly and outwardlydiverging sides from which extend upwardly and inwardly lines and terminating in a rounded tread. The body portion of this tire is designated in the drawings by the reference numeral 1,. and this tire is retained upon its seat in the rim of a wheel bymeans of circurriferentiallyarran ed retaining wires or hands {2, 2;althou any other type of fastening or holding device may be employed-which will be they will be self-cleanin openings are made with agreater external that these membersj, 5, yield more easily to 4, I prefer to make them of such a design that v by this is meant that if forany reason rirt or similar sub- In earryiiiginto eflcct my invention, the vals with transversely-arranged notches or i the drawings by the. 3, 3, andthe placing oftire serves to divide the greater extent under a given amount ofcornf pression than would be possible were the tread portion continuous instead of bQlDQlL? bein due-to the fact '85 The existence of these" which is a result greatly sought after by I.
